MRI + hangrip: Hangrip exercises, oral glucose during MRI scans
Saline and oral glucose: Saline infusion oral glucose during MRI scans
Study summary
This project will describe the mechanisms of action and the relative contributions of GIP to changes in gastrointestinal blood flow induced by oral glucose and endogenous GIP with the use of a receptor antagonists GIP(3-30)NH2 in patients with postprandial hypotension.
